OS X El Capitan on Unsupported Macs

[Doctor_Pi]

I tried MacPostFactor 2.0.1. I was able to create a MCPF El Capitan Install USB key and boot from it. I selected the option of installing El Capitan on the iMac's own hard drive. After a while the computer restarted and it booted into Mac OS X Utilities.

I tried it a second time but the same thing happened so I restored Lion from the Time Machine backup.

OS X Extractor crashes on startup. It doesn't appear to be version 1.34 even though the installer claims it is.

I'm willing to try installing El Capitan because I'm not having much luck installing Linux on this iMac.

Update: Yes, OS X Extractor is 1.34.

 

[Elijahg]

I've been unable to get MCPF to work, the first stage works, and I can restart from the Installer USB stick/partition. But I get a kernel panic after a short while.

I've tried with a different drive a fresh installation of El Capitan, following Skyfly's guide... and El Cap starts up and runs! ...and then KPs. Each time a different KP, it is quite unstable . It does only seem to crash when I've used a USB device though, so might try VNC only.

(Mac Mini 2,1)

 

[Elijahg]

Seems that MCPF doesn't work to install 10.10 either. The installer says it doesn't know what's wrong; but the installer log says that OSInstall.pkg can't be opened as the current OS is too new; i.e. the installer OS is 10.11 and needs to be 10.10 for OSinstall.pkg to be run. However, after examining SystemVersion.plist on both the installer and destination drives; the destination drive has 10.11 and installer drive has 10.10. Something's quite broken!

El Capitan's Disk Utility didn't erase the destination drive after I made an attempt with El Cap for some reason, so the above doesn't apply... Oops.

I keep getting error 1 on my MacBook 3,1. I've tried erasing and reinstalling loads of times and I have also redownloaded the .app from the App Store. I've tried to do a usb install but its says my 8gb drive is too small. Any one any ideas? Thanks

I'm trying to install El Capitan via MPF but I can't select any "type to install" option

Hello,

Hello, Elijahg.

What happens is that boot.efi is not OK. The one I've attached to the #502 post is the one that lets me to boot Yosemite in my MacBook 2,1, and it's EFI32, from MacPostFactor. I tried what you are doing, changing the PlatformSupport on the boot.efi from El Capitan's Pike's boot.efi branch and recompiling, and it didn't work neither. Have you done this process from El Capitan branch, or from Yosemite branch one?

I suggest you to use MacPostFactor to install Yosemite in your computer, so you can see if boot.efi from MPF is ok for you. If Yosemite, with that boot.efi, boots on your machine, you should be able to copy that boot.efi and, using it instead of my boot.efi, boot El Capitan following the method I described.

 

[schreiberstein]

I was able to install El Capitan onto my MacBook 2,1 Mid-2007 (GMA 950), but disabling SIP/csr was not possible using the 2014 boot.efi from MacPostFactor. The system worked, but the Intel GMA 950 kexts obviously didn't load. I tried to change the nvram values using a Snow Leopard CD, but these variables were not processed by that old boot.efi file. It worked properly with the 2015 boot.efi from pike (audio, video, wifi, etc.), but this also introduced instability. Pike's boot.efi didn't even work properly on Yosemite on this MacBook. Random restarts. It's all up to the boot.efi. My verdict: One would have to take the original code from the MacPostFactor 2014 boot.efi and just apply that ONE change for the csr-active NVRAM variable. It would be a good idea to insert 0x67 (ALL DISABLED) into the boot.efi anyway, since it's a huge hassle to inject the proper NVRAM variables after a PRAM-reset. I have no clue what source the MacPostFactor 2014 boot.efi was built from. I am now restoring my Yosemite image... Might try it some other time.

EDIT: I installed everything manually. No MacPostFactor involved.

 

[skyfly555]

Links will be updated to view MacPostFactor 2.0.1 and OS X Extractor 1.34 (both with fully corrected El Capitan Support and bug fixes) along with @skyfly555's method. If you have any trouble similar to kernel panics I'm MacPostFactor, email MLforAll directly at voolfy@me.com. USB Kexts will have to be changed a little in Sierra but I will include the package in OSXE. We can discuss this in the Sierra thread.
The OS X Hackers site will soon get a much need redesign in light of some confusing of where certain stuff was.
I apologize for the extremely long wait for this. This particular OS required a lot of work regarding ore linked kernels, updated USB Kexts rules, updated Graphics Kext rules, and SIP which made it a struggle to figure out how to get it running and what goes wrong. I, myself, have learned a lot of new material from many members of MacRumors as well as my professor at my college.

Hello, TRMJIJ, thanks for your work.

I've tried MCPF v2.0.1 with my MacBook 2,1. It doesn't work (many attempts, first directly to the HDD, second creating the installer and doing a clean install formatting the whole HDD drive...).

What happens?
I arrive to the screen I'm attaching, after some minutes it reboots. I arrive again to this screen, it reboots, and this happens all the time. The installation process cannot finish.



One question: Have you worked upon the GMA 950 kexts to do the same modifications you did into the GMA X3100 kexts to make them compatible with El Capitan? Your GMA X3100 kexts work like a charm into my hackintosh, but the GMA 950 kexts I have work very slow and it's like not having them under El Capitan on my MacBook 2,1

Thank you again,

PS: I've realised the USB MCPF installer has destroyed my Bootcamp partition... No problem, I have a Winclone backup.

I did apply 0x67 among other changes in the Boot.efi for El Capitan however they refused to boot for certain 32bit Macs. Assuming that things changed over the updates, I can try again but I'll need to fix compiling issue with VB.Net. The csr variable doesn't exist in Yosemite. We can ask Pike for his source code.

Hello,

With the steps I've described SIP cannot be disabled. Until TRMJIJ and the other developer don't modify GMA 950 kexts, they work slow with El Capitan, but with the boot flags I've described, concretely, the -no_compat_check one, they should be loaded on your computer. I've tried to create a recovery volume, and I got it with some tricks, but it doesn't let me to disable SIP, because I don't know how to create a correct prelinked, El Capitan Recovery Volume thinks I'm booting from El Capitan directly if I copy El Capitan prelinked (the one we generate on step 11 of the tutorial) directly to Recovery partition.
As I've stated into another post MCPF v2.0.1 doesn't seem to work with our Mid-2007 MB 2,1.

One question: Have you tried using the boot.efi I've attached to the tutorial? It works nice with my MB 2,1, no hangs or kernel panics, very stable.

Thank you very much for your answer!!! Desiring to see this graphics kexts update soon!

Related to boot.efi, El Capitan Pike's EFI doesn't work with my MB 2,1. I needed to use Yosemite Pike's EFI instead. As you know, it works, but SIP cannot be disabled.

So, I understand what happens with MCPF v2.0.1. El Capitan Pike's EFI doesn't boot with the vast majority of EFI32 Macs, it seems to be very Mac Pro oriented. I tried to change it, recompiling it with Visual Studio and it didn't work, it rebooted all the time too. I even have an issue opened on GitHub related to this but Pike hasn't answered to it yet.
That's why my MB 2,1 reboots, it's what happened to me while I was trying the method I've described using that El Capitan boot.efi. Until I didn't change boot.efi to the old Yosemite one, I didn't have success installing El Capitan.
Thank you very much,

Ok, tried several times to install ElCapitan on MacBook 3.1 with MPCF 2.0.1. After everything is done in MPCF and program infrom me to restart, I hit "Restart Now" button and on restart holding Alt/Option to check what's changed. i have three partitions: Mac HDD (OSX 10.7.5), Recovery HD (Recovery for 10.7.5) and "Install Recovery on Capitan (Capitan is the name of partition that i want to install 10.11 on). After choosing this last one, my MacBook booting to 10.7.5. Doing something wrong or not? Also-tried two versions of App (Clean 10.11.0 and updated 10.11.4) and still encounter the same problem. Someone can help?

 

[enri1357]

Many thanks for the hack and guide. My Macbook2,1 is running 10.11.6 following skyfly's guide #502.

I want to know about adjusting screen brightness. When I want to adjust the brightness via hotkey F1 / System Pref Displays / other software, the brightness level is always highest, which is too bright when using at night.

Is this a known limitation?

Edit 1:-------------
After I post this reply, I read there are new post that comes up today, and want to add my info.

boot.efi: yes the Pike's 10.11 one will get me KP. So now all the files are from skyfly's post.
GMA950 kext: really looking forward to the coming update, hopes it can add the brightness settings.
MacPostFactor: Reboot while installing, then come back to install screen again

Now checking to see if I should get a SSD and swap the 512MB to a 2nd 2GB ram (currently 2GB+0.5 GB). skyfly, which brand/model of ram do you use for your 4GB config?


Edit 2:--------------
USB: port can use mouse, but the USB storage does not - it cannot be detected; blank in system information > USB (no usb root hub, no device even when USB mouse is usable); When booting with USB drive, I can see the USB drive in Finder.
Any clue about this issue?

Also, applied the Animation Disable package, but the system still have animation (and seems slower too, no help with uninstall, need to clone back the ext usb image to get fix)
Turns out to be even slower when I recover the image.
Open App is fine, but the Launchpad animation and Dock Folder in Grid (pre-launchpad style) is extremely slow
The command below helps the Launchpad:
defaults write com.apple.dock springboard-show-duration -int 0
defaults write com.apple.dock springboard-hide-duration -int 0
killall Dock

Well, clicking the "Other" folder inside Launchpad is extremely slow...even after disabling Window Animations.

Edit 3:-------
Better not reset the PRAM because I tried resetting it and no matter how I change the settings, even the non-related ext USB boot not able to see the login screen, not until I completed Lion reinstall. After that, the USB can boot back....

skyfly, I saw your thread on Clover, can you tell me some information on what you have tried not work? I want to try on clover and found that you have a thread there

You don't have to do anything after you skip de adfly... the MPF will show you the configuration screen after the installation is done. Yo should try erasing the partition and doing again the process.

Thank you for following the guide, nice to see it's helping you. And thank you for checking 10.11.6. When I created the guide I did everything with 10.11.5.

Hello, enri1357, yes, this is a known limitation. If you have, for example, Bootcamp, or another OS X version and you can boot from there, it's supposed the brightness you adjust on Windows/Other Mac Os X will be maintained after rebooting to Capitan, but i've never tried it. Another option is this, but i've never tried it, neither: http://www.manzanaslibres.com/2015/12/definir-brillo-en-el-arranque-del.html

Thanks for checking boot.efis. I don't care about memory, I've tried several brands and they all work. Now I have 2 GB from Komputerbay-Amazon, and the other two comes from my Acer 5315, they are Kingston. You just need it to be DDR2, SODIMM, and not much more.

Any clue about this issue?

Yes, this seems to be a bug from Beta USB kexts we are using (yes, I checked the USB kexts people are using to hack Sierra and they don't work). But there's a solution.
When you boot the computer, connect your external HDD/SDD to the USB before booting. If you do this, external storage is recognised, no problem. But if you connect it when you have already booted, it doesn't work. I don't know why this is happening and/or if OS X Hackers will modify these kexts to avoid this to happen.

Also, applied the Animation Disable package, but the system still have animation (and seems slower too, no help with uninstall, need to clone back the ext usb image to get fix)
Turns out to be even slower when I recover the image.

These are great things, disabling animation and so on, but the problem are GMA950 kexts. They are loaded in compatibility mode, from Yosemite, not well adjusted to El Capitan.

skyfly, I saw your thread on Clover, can you tell me some information on what you have tried not work? I want to try on clover and found that you have a thread there

I tried to install Clover, UEFI Clover, Legacy Clover, rEFInd, and they all seem not to boot the system. I tried Clover because of the great injection of SIP disabler (0x67) and other kexts.

One more thing: if you see someday your MB2,1 is not booting and hanging, this could happen if you got corrupted the famous folder com.apple.kext.caches
This folder is the trick we are using to bypass SIP. If it is there, Capitan doesn't check the kexts it's loading, supposing they are OK. If El Capitan has to rebuild this folder, audio/video kexts are not loaded and, sometimes, USB kexts neither! So it cannot boot.
Hence, I recommend having a bootable Capitan external drive to be able to boot and copy this folder if it disappears (this is the famous step 8a).

I hope somebody will improve Yosemite Pike's boot.efi and we will have SIP disabled and we will not need to have this caution, although I always have a Carbon Copy Cloner image so I can boot from an external drive (you never know what can happen and when).

 

[enri1357]

Thanks for replying.

Today when I turn on the Macbook2,1 to adjust brightness in Bootcamp, the sound and graphics gone (perhaps kext not load)
Interestingly, when I want to fix the system under this condition, the usb memory can be accessed without plugging it in before the system bootup. I suppose some kext I put in S/L/E on the system is not needed, but my hdd is too slow, need time to dig further....

A quick fix to my problem is on the kext caches (as expected), and I use CCC to clone the ext usb's com.apple.kext.caches back to the internal hdd and reboot

BTW, where did you put the boot.efi in EFI partition Clover folder?

The kexts we have thanks to compatibility-mode are GMA950 (video) and AppleHDA (sound). They are the two ones that disappear when something "strange" happens, as booting from Windows or whatever, and then we need to restore the kext caches, as you have done Your observation is very interesting (I put it in bold letters-quote), I have just realised the same happens to me. I don't know what's the reason, maybe some incompatibility among USB and video or audio kexts?

BTW, where did you put the boot.efi in EFI partition Clover folder?

I tried /CLOVER/DRIVERS32, /CLOVER/DRIVERS32UEFI, /CLOVER/DRIVERS64, /CLOVER/DRIVERS64UEFI, /CLOVER/kexts/other, /CLOVER/kexts/10.11

After thinking a lot about it, I finally discarted Clover.
But there is an idea that could be done and Clover should boot, but I simply didn't know how to do that.
The idea: You have Windows on your Mac because Windows is installed in legacy mode thanks to bootcamp. Because Windows is not booting in UEFI mode, Windows thinks there is a BIOS there, and this is what Bootcamp does (cheating Windows to believe there is a BIOS and a normal PC there).
So, Legacy Clover should work, as in my old hackintosh (http://www.insanelymac.com/forum/to...007-acer-aspire-53155715z-unsupported-laptop/). We just need to have our Mac thinking it's going to boot Windows, not Clover-Mac OS X.
Am I explaining it well? It's like if you wanted to clone El Capitan to your Bootcamp partition, or the other way, clone bootcamp way of booting to your Capitan partition. Then, Legacy Clover should work.
Note: This idea can seem stupid, but this works inversely (real mac -->hackintosh), as I said in my insanelymac post: "I tried to install Yosemite before (...) on the 5715z. How did I do that? I Carbon Copy Cloned my hard disk from an old Macbook 2,1 (not supported by Yosemite, but Yosemite installed thanks to MacPostFactor from OS X Hackers), I installed Chimera 4.0.1 (Chimera is a bootloader, like Clover)". As you see, bootloader is the key. Chimera told Mac Os X there was an EFI there and it booted on my hackintosh. To boot Legacy Clover on our real Mac, we need to tell Mac Os X there is a BIOS there and to use bootcamp to boot from it.
I didn't try to get this done because I had spent too much time on it and I was tired, just had energy to create the post #502 tutorial And I'm not sure what to do to put the idea into the realm of reality.

 

[enri1357]

Although I like clover a lot (iMessage, disable SIP, etc), and don't want to patch osx like what I did ever since 10.6, the resource left on clover+real mac is just limited. (you know, the major forum on clover is gone)

I looked at the MacPro thread on 10.10 for the first 20 pages, they listed some issue I face such as selecting boot part inside clover but no response and require bless (but that does not help me situation) and what they did is also replacing the boot.efi in the system partition of osx, which defeats one main advantage: no patch to osx partition. (the facetime thing is another area)

There is no mention about clover in the 1st post in 10.11 MacPro thread as well.

To completely understand what they did, need to spend time on all 250 pages 10.10/11 combined. @.@

So I suppose enhanced graphic kext and ability to disable SIP are more important than other things at this stage.....

Yes, I think the same, too.
In this very moment TRMJIJ is working on solving troubles people are facing with MCPF v2.0.1. In my opinion, these troubles are mainly related to boot.efi.
After that, OS X Hackers team will work on the GMA 950 drivers.
So, very soon we will have these 2 things solved.
Once this done, we have to see if we have the USB external drives issue or it's solved, too. Because this seems to be related to GMA950 kexts or ApleHDA.kext

Thank you very much!

I keep getting error 1 on my MacBook 3,1. I've tried erasing and reinstalling loads of times and I have also redownloaded the .app from the App Store. I've tried to do a usb install but its says my 8gb drive is too small. Any one any ideas? Thanks

Can't help with the first issue. The instructions for creating a USB install key do say they require 15 GB of available space.

Are u using yosemite's boot.efi? U can check post #502.

 

[s4keru]

So yosemite boot efi is the key to install and have working ElCap on some unsupported machines?
Also, can someone write about what is working and what is not on these machines please?
I have read somewhere here that USB stick will only work if I put it in before booting my MacBook.
Can anyone write a list of things like that?
Thank You

Check post #502 and download that boot.efi, replace boot.efi you have with this one, and install it as explained. Tell us what happens then: it should boot.

I have tried installing on a 2,1 and 3,1 MacBook using MCPF 2.01 and have had no luck at all I now keep getting kernel panics. I have tried doing a usb install but it won't even boot to the installer and I have tried using the efi.boot from my Yosemite install again with no luck. I have tried post 502 procedure and again no luck. Has anyone any more Ideas for me to try. Thanks Jon

I have tried post 502 procedure and again no luck. Has anyone any more Ideas for me to try. Thanks Jon

Mb 2,1 needs Yosemite from post #502. Mb3,1 needs another boot.efi from your Yosemite OS X Hackers installation. Mb3,1 boot.efi will not work on mb2,1. Be sure what boot.efi u are using. If method is 502, be sure kext.caches folder is created. If you do 502 again with your 2,1 using the files attached and then explain *exactly* what happens, maybe I can help you.

Are u using yosemite's boot.efi? U can check post #502.

So yosemite boot efi is the key to install and have working ElCap on some unsupported machines?
Also, can someone write about what is working and what is not on these machines please?
I have read somewhere here that USB stick will only work if I put it in before booting my MacBook.
Can anyone write a list of things like that?
Thank You

To know limitations read posts from #502. Yes, yosemite's boot.efi is the key. Procedure #502 is the only one now is working. OS X Hackers are now working to fix MCPF.
